SPECIFICATION forming part of Letters Patent 1%. 733,390, dated July 14, 1903. Application filed Octoberlii, 1902. Serial No.l27,'798. (Nomodel.)

To 6L wltom it may concern:

Be it known that I, IVIORRISON C. HAMIL- TON, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Push-Cars, of which the following is a specification.

This invention relates to push-cars, and has for its object to provide a dumping push-car which may be converted into and employed as an ordinary car.

Another object of the invention is to provide means for assembling a dumping-box and a push-car in such manner that the parts may be readily assembled and disassembled and in such manner that the assembling and disassembling may be accomplished with a minimum of labor, and a further object is to provide an improved and efficient dumpingcar.

In carrying out my invention I employ a flat push-car of any ordinaryor convenient construction and upon one or both sides thereof provide suitable eyes or holding devices and provide a dumping-box which may have one of its sides open, which box will be provided on its bottom, preferably a little past the center, with holding devices constructed to mate with those upon the car and which holding devices may be hooks of peculiar construction and curvature whereby the box can only be removed from the car when in certain positions and responsive to certain applications of force, and when in such positions the hooks will readily slide in and out of the eyes. By this construction one man on each side of the box, if it is of a size fitting the ordinary push-cars, may readily raise it up, it then being in the easiest position to lift. For certain purposes, however, the hooks may be so constructed that a straight raise of the box while it is flat will owing to the conformation and the cam action of the peculiarly-formed hook permit the hook to slide out and in so doing move the box slightly sidewise against the force which is raising it.

Ordinarily the weight of the inside end of the box and the mode of loading the same will hold it in position until it is dumped, or some convenient means may be employed for securing the box in position.

Heretofore it has .been necessaryfor contractors to use specially-constructed cars, if they desired them, for dumping purposes; but these cars are not adapted to the general uses of the railroad company for their repair gangs, nor are they absolutely adapted to all uses of the construction contractor, because it frequently happens that it will be desired to use cars to move rails, ties, and similar material, which with the specially-constructed dumping cars cannot be done conveniently or without injury to the cars; but in my device it is merely necessary to dismount the box and the car in an ordinary pushcar. Thus economy of number of cars is had and also convenience, it being much easier to dismount a car which is at hand than to get the car away and bring up the desired form of car. It has also been the practice in some places to place a box upon a push-car and when it was at the point desired to unload to push the box 0d the car with crowbars. This mode was not feasible, because it requires more men to dump the box than it does with my device, and also there is less certainty as to where the load is going to be dumped. In pushing the boxes oif the cars with crowbars the boxes and the car-floors are frequently injured and their lives shortened.

With my device in repairing embankments where the damage frequently happens between the ends of the ties the material can be dumped right where it is wanted, and the construction is such that the bottom of the box Will swing down and act as a shield for preventing the material from getting on the wheels of the push-car and from getting upon the rails. So it will be readily seen that the device saves labor, is more economical as to the amount of labor employed in distributing A the material dumped, and also is more efficient and does a cleaner job. It frequently happens that the repair gang on a railroad have to remove their cars from the track and the present quickly-operating dumping-'box top view of a form of car constructed according to my invention. Fig. 2 is an end view thereof, and Fig. 3 is a detail of a form of pivot-hook which may be employed.

The push-car, (designated in a general way by A,) is shown as comprising a floor portion or top 4, mounted on wheels 5, which are connected with an axle 6 and rest upon rails '7, (shown as placed upon cross-ties 8,) to which caris shown attached adump-box, (designated in a general way by 13,) which in the present instance comprises a flooring 9, side boards 10 and 11, and an end board 12. The car may be provided with pivot connections for the box, and for such purpose at each end of the car-floor is shown a metal strap 18 and in the center of the car a strap 14:, the number of straps, however, being determined by the weight and construction of the device. Each strap is shown provided with an eye 15, and the bottom of the box is provided with mating pivotal devices, shown in the present instance as hooks 16, bent in such a way as to prevent the box when in the flat or carrying position from sliding off the car, and also which will permit the box'to be detached by hand from the car when it is in a substantially upright position, as indicated by dotted lines in Fig. 2. For the purpose of holding the box from tipping it may be provided with suitable retaining devices, such as a chain 17, secured to the box and provided with a link 18, which will take over a stud 19 upon the car-body.

If it is desired to use the box as a derrick box or tray, it may be provided with suitable eyes 20 at the sides and ends, in which instance the derrick-chains may be attached to the eyes, and upon the disconnection of the link-stud the box may be raised from the car, the hooks permitting the box to yield sidewise in being drawn out. The sides of the box may be provided with handles or grabirons 21 for. convenience in operating the box.

The box or receptacle is shown as pivoted to the car-floor at the side and past the wheels and track and as resting upon the fiat floor. The pivot-point is shown as so located that the tray or box upon being dumped may assu me a position transverse to the car-floor and. will balance back into the carrying position. The point of pivoting and of securement are so positioned relatively to the car and wheels that the leverage is applied to the car as on a short arm of a lever and the car will not be tipped over when loaded properly.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination with a fiat-top pushcar, of a detachable dumping-box; and pivotal connection therebetween normally constituted for disassemblage.

2. The combination with a hand push-car, of a dumping-box pivoted thereto, on a perpendicular plane exterior of the perpendicw lar plane of the sides of the car and fixtures carried thereby, by pivotal connections be tween the car and box normally constituted for disassemblage, and adapted to swing on such pivot at the side of the car and dump its load adjacent to the rail on which the car may stand.

3. The combination with a push-car, of a dumping-box pivoted thereto at its edge by means of a hook taking into an eye whereby the car may be relieved from the box by upward movement of the box when it is either in a fiat position or in an upright position.

4. The combination with a push-car provided with a fiat top and complete as a pushcar, of eyes thereon, a box provided with hooks adapted to take into such eyes, and means for holding the box upon the floor of the car.

5. The combination with a car-floor, of runhing-gear supporting the same; a box or tray riding upon the car-floor; and means for dismounting the box or tray and embodying a set of pivots comprising two sides and normally constituted for disassemblage,the members of one side of the set secured to the car and the members of the other side of the set secured to the box.

6. The combination with a car-floor, of runninggear supporting the same; eyes secured to the floor at one side; a box or tray adapted to ride upon the floor and partly overhang the same; hooks secured to the bottom of the tray at the region of overhanging and constructed to mate with the eyes and form pivots and means of attachment.

7. The combination with a flat car having wheels on each side whose treads are adapted to run on a rail, of a receptacle; and pivotal connections between the receptacle and the side of the car parallel with the rail and beyond the plane of the tread of the wheel and every portion of the car, and normally constituted for disassemblage.

8. The combination with wheels that run on rails, of a car-floor supported by and overhanging the wheels on each side; a box pivoted to permit the same to be readily dismounted to the overhanging portion of the floor at one side and having a portion adapted to lie upon the floor and a portion to overhang the same; and means for securing the part lying upon the floor to the floor at a point nearer the wheel over which the box rides than the other wheel, whereby the leverage of the box and load upon the car will be exerted as power applied to the short arm of a lever.

9. The combination with a car-floor, of running-gear supporting the same; a receptacle adapted to lie partly upon the car-floor and partly overhang the same; eyes secured to the edge of the floor beyond the wheel of the car; hooks in the bottom of the receptacle and adapted to mate with the eyes for forming pivots and means of attachment and detachment; and means for holding the receptacle upon the floor of the car, the organization being such that the receptacle normally of the hooks and eyes being such that upon lies in the plane of the floor of the car but raising the box with the derrick-attaching 16 may turn upon its pivots in a plane transmeans the hooks upon the bottom thereof will verse to the plane of the floor. slide out of the eyes upon the car.
